Problems with the double Bed

Since the new update two of my sims can no longer sleep in the same double bed at the same time. Whenever one is already sleeping in it the other can´t get in because the other one is somehow blocking them. I switched beds to see if that changes anything but the same issuse keeps happening. There is nothing blocking the bed. I made the sims walk to the other side of the bed but they just walked to the side where the other was sleeping.
